BNC T-type adapter

Abstract

A BNC T-type adapter includes a T-shaped hollow housing with a common branch and left and right branches that extend from two sides of the common branch and that are communicated with the common branch. The common branch has a twist-lock member secured thereon. An internal conductor is disposed in the housing and includes a vertical conductor that extends into the common branch and a horizontal conductor that is connected to the vertical conductor and that has left and right parts which extend respectively into the left and right branches. Two insulator units are sleeved respectively around the left and right parts to position properly the horizontal conductor within the housing. The horizontal conductor further has a plate-like intermediate part provided with a retaining projection that protrudes upwardly therefrom and a pair of rectangular plates that project upwardly from two sides thereof. Each of the rectangular plates is formed with an inwardly and downwardly inclining resilient fin. The vertical conductor has an intermediate section that is clamped between the resilient fins and a lower end that engages the retaining projection.

I claim: 
     
       1. A BNC T-type adapter including a T-shaped hollow housing with a common branch and left and right branches that extend from two sides of said common branch and that are communicated with said common branch, said common branch having a twist-lock member secured thereon,   an internal conductor disposed in said housing and including a vertical conductor that extends into said common branch and a horizontal conductor that is connected to said vertical conductor and that has left and right parts which extend respectively into said left and right branches, and   two insulator units sleeved respectively around said left and right parts to position properly said horizontal conductor within said housing,   wherein the improvements comprise:   said horizontal conductor further having a plate-like intermediate part provided with a retaining projection that protrudes upwardly therefrom and a pair of rectangular plates that project upwardly from two sides thereof, each of said rectangular plates being formed with an inwardly and downwardly inclining resilient fin; and   said vertical conductor having an intermediate section that is clamped between said resilient fins and a lower end that engages said retaining projection.   
     
     
       2. The BNC T-type adapter as claimed in claim 1, wherein said retaining projection is a cylindrical stud. 
     
     
       3. The BNC T-type adapter as claimed in claim 1, wherein said intermediate section of said vertical conductor is formed with an annular groove which engages said resilient fins. 
     
     
       4. The BNC T-type adapter as claimed in claim 1, wherein said lower end of said vertical conductor is tapered and is formed with an engaging recess that receives fittingly said retaining projection therein. 
     
     
       5. The BNC T-type adapter as claimed in claim 1, wherein said lower end of said vertical conductor is formed as a tapered tube with axially split parts that engage said retaining projection. 
     
     
       6. The BNC T-type adapter as claimed in claim 1, wherein each of said left and right parts has a first end connected to a respective end of said intermediate part and a second end provided with a clamping unit. 
     
     
       7. The BNC T-type adapter as claimed in claim 6, wherein said clamping unit is a tapered tubular unit with a number of axially split parts. 
     
     
       8. The BNC T-type adapter as claimed in claim 6, wherein said clamping unit is a downwardly projecting protrusion that is formed by punching each of said left and right parts. 
     
     
       9. The BNC T-type adapter as claimed in claim 6, wherein said clamping unit is a slanted resilient conducting strip which is formed by punching each of said left and right parts.
